Description

This application claims benefit of priority under 35 U.S.C. § 119 to French Patent Application No. FR 06/007157, filed Aug. 4, 2006, the contents of which are also incorporated herein by reference.
The present disclosure relates to a cosmetic composition for the treatment of keratin fibers, for instance human keratin fibers such as the hair, comprising at least one lambda-carrageenan polysaccharide, at least one specific polyol and at least one specific additive, to a process for cosmetic treatment using the composition, and to the use of this composition for hair care.
In the hairstyling field, for instance among hair products for use in shaping and/or holding the hairstyle, hair compositions generally comprise a solution, most commonly alcoholic or aqueous, of at least one fixing polymer as a mixture with various cosmetic adjuvants.
These compositions can be in the form of hair gels or mousses which are generally applied to wetted hair before blow-drying or drying is carried out.
Hair gels may comprise at least one thickening polymer or gelling agent in combination with at least one fixing polymer which most commonly have the function of forming a film at the surface of the keratin fibers to be fixed.
Recently, carrageenans have been used as fixing polymers in hairstyling gels or in aerosols. In fact, it is known practice, from document EP 1 199 064, to use a carrageenan or a mixture thereof and a specific additive in order to obtain a solid and stable gel for hair treatment.
Carrageenans are polysaccharides which constitute the cell walls of various red algae (Rhodophyceae) belonging to the Gigartinaceae, Hypneaceae, Furcellariaceae and Polyideaceae families. They comprise long anionic polyelectrolyte galactanic chains. Their molecular mass can be greater than 10⁶. These linear polymers, formed from disaccharide units, are composed of two D-galactopyranose units alternately linked by α- and β-linkages. They are highly sulphated (20-50%) polysaccharides and the α-D-galactopyranosyl residues can be in 3′,6′-anhydro form.
Initially, carrageenans were divided up into two families according to their solubility in potassium chloride (KCl). The fractions soluble in KCl were denoted by the prefix “kappa”, while the term “lambda” was reserved for those which are insoluble. Later on, the classifications were based on the number and the position of sulphate groups and also the presence of a 3′,6′-anhydro bridge on the β-D-galactopyranosyl residues. This resulted in four major families: κ, λ, β, ω.
The various types of carrageenans do not exist in the pure state, but in the form of hybrids. Thus, in the natural state, κ- and ι-carrageenans are in the form of a kappa-iota hybrid, but one of the two structures may predominate over the other. The κ-ι hybrid state of a structure can be elucidated using specific enzymes which make it possible to enrich or decrease the content of one of the two forms. Carrageenans can coexist with their precursors. Carrageenans belonging to various families can coexist in a hybrid structure; for example: carrageenan of Euchema gelatinae: a hybrid of β-carrageenan, the major component, and of κ, γ-carrageenans.
The use, in hair care, of λ-carrageenan type polysaccharide makes it possible to obtain hairstyling gels with good fixing properties. However, the film formed at the surface of the hair is quite friable and does not allow the shaping to be held over a long period of time.
There exists, therefore, a real need to find cosmetic compositions, for instance for hairstyling, which make it possible to improve the properties of hold of the hairstyle over time.
Surprisingly and unexpectedly, the present inventors have discovered that, by combining at least one λ-carrageenan with specific polyols and specific additives, it is possible to obtain compositions whose hold over time may be improved, while at the same time obtaining a very limited friability of the fixing film, solving one or more of the problems mentioned above. Further, it has been observed that, in this composition, the lambda-carrageenans make it possible to obtain gels which have a better texture, which are less brittle and less hard and which are easier to apply.
One aspect of the present disclosure is therefore a cosmetic composition for the treatment of keratin fibers, for instance human keratin fibers such as the hair, comprising, in a cosmetically acceptable medium:
at least one lambda-carrageenan polysaccharide;
at least one specific polyol other than carrageenans; and
at least one additive chosen from a silicone, a fatty substance and a fixing polymer other than carrageenans.
Another aspect of the present disclosure is a cosmetic treatment process using the cosmetic composition as disclosed herein.
A further aspect of the present disclosure is the use of the cosmetic composition as disclosed herein for fixing the hair or for hair care.
Other subjects, characteristics, aspects and benefits of the present disclosure will emerge more clearly on reading the description and the examples which follow.
As disclosed herein, the word “hairstyling” is understood to mean the fact that the shape of the hairstyle is fixed and/or held.
The composition according to the present disclosure comprises at least one lambda-carrageenan polysaccharide.
According to at least one embodiment, the lambda-carrageenan polysaccharide used according to the present disclosure is not chemically modified.
For instance, according to at least one embodiment, the molecular weight (MW) of the polysaccharide ranges from 100,000 to 1,000,000. Even further, for example, the molecular weight ranges from 250,000 to 800,000.
By way of lambda-carrageenan polysaccharide that may be used in the context of the present disclosure, non-limiting mention may be made of Satiagum UTC 10 from the company Degussa and Welgeenan ED 1039 from the company Eurogum.
The lambda-carrageenan polysaccharide can be present in the composition in an amount ranging from 0.1% to 30%, for instance from 0.2% to 20%, and even further, for example, from 0.5% to 15% by weight, relative to the total weight of the cosmetic composition.
The polyols that can be used in the composition according to the present disclosure contain, in their structure, at least three hydroxyl (OH) groups.
For instance, the polyols according to the present disclosure can be chosen from simple polyols, monosaccharides, disaccharides, oligosaccharides and polysaccharides other than carrageenans.
As used herein, the term “simple polyols” is understood to mean compounds comprising a linear or branched alkyl or alkenyl chain containing from 3 to 100 carbon atoms, comprising at least three hydroxyl (OH) groups. According to at least one embodiment, this alkyl or alkenyl chain is C₃-C₂₀.
By way of example of simple polyols, non-limiting mention may be made of glycerol or 1,2,3-propanetriol, 1,2,3-butanetriol, sorbitol, 3-methyl-1,3,5-pentanetriol and 1,2,4-butanetriol.

The at least one anionic and cationic groups can be linked to the same reactive site of the starch molecule or to different reactive sites; according to at least one embodiment, they are linked to the same reactive site; and include, for instance, chemically modified or nonmodified, nonionic guar gums. The nonmodified, nonionic guar gums are, for example, the products sold under the name Vidogum GH 175 by the company Unipectine and under the name Jaguar C by the company Meyhall.
The modified nonionic guar gums that can be used according to the present disclosure are, for instance, modified with C₁-C₆hydroxyalkyl groups. By way of example, non-limiting mention may be made of hydroxymethyl, hydroxyethyl, hydroxypropyl and hydroxybutyl groups.
